As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Recently I had to refresh Windows 11 on my Dell desktop. It defaulted to McAfee antivirus. I uninstalled McAfee and reinstalled Norton 360 which I had before. I reinstalled Firefox. I have version 123.0.1. I imported my FF bookmarks after exporting them from another computer. Now, FF remembers my IDs but not my passwords. When I log in to a website, FF offers to save my password and when I click yes it pops up a bubble saying "Password saved!" However, next time I go to that website, although it remembers my ID, it does not recall my (supposedly saved) password. In this support site, I see most users with this problem say FF will not remember either their IDs or passwords, whereas FF remembers my IDs, so my problem may be different. In FF help, I see that another password manager could be keeping FF from saving passwords. To the best of my knowledge I have never used another password manager. What is keeping FF from saving my passwords, while remembering my IDs? Is there a Windows Registry setting or a FF About:Configuration setting I need to change? Is re-installing FF a last ditch option?

Hi,

For as long as I can remember I've been able to ctrl + click in the "text area" beneath the link in DuckDuckGo search results and Firefox would open a new tab and switch to that tab automatically; but if clicking on the link itself Firefox would open the link in a new tab in the background. This was a priceless feature until today with the 123.0 update. Now ctrl + left click in the text area opens a new tab in the background but does not switch to it. I've been able to confirm this is only effecting v123 on all both linux and windows.

Hoping somebody here might be able to suggest to development returning this feature back to Firefox or help me figure out a way to set this option manually myself.

Thanks!

My Firefox has gotten so buggy lately I can't use it. I'm writing from Edge. THere are numerous issues. The sign in process got messed up a couple months ago. IT asks for email address, then doesn't provide password screen option, takes forever to send email, and then sometimes repeats itself. Tabs crash and clicks fail to work randomly. Out of desperation I reset my Firefox password and that seemed to help temporarily, but not enough. So what's happened and how to fix??? Thanks.

Hi all, In the past I was using Chrome and I have decided to move back to Firefox because I didn't like certain trends of that browser...now...the thing is...I like to use Yandex, but in Chrome -until a certain point- I was able to alter its settings to force default English language for it.

Firefox seems to have Yandex set as default...you cannot alter it and you cannot delete any of the default engines (i.e., because if it is loaded, you seem unable to try add it as custom search engine with your chosen parameters), but seems that the Mozilla developers had the brilliant idea to add it with the default settings...which is in Russian...

...and you look into Extensions and all the people writing extensions seemed to have the same idea...

Now...fine that Yandex is mostly for Russian people, but why English-speaking users to be forced with the default search in Russian and being completely denied any possibility to force the English language on Yandex (as it is fully possible if you were able to tweak the search parameters...but Firefox isn't allowing to do, because the only thing we have is a dumbed down interface with a list of search engines!)...

...alternatively...why not allow to force our favored language parameters to ALL search engines by default?

( That would mean that one could have Google, Bing or Yandex in a different language of our choice....but that change would need to be implemented on developer side...)

ONE EXAMPLE - This morning I wanted to sign into my Navy Federal Credit Union account. I got the following error message:

You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/mfa.fcc" on this server.

Reference #18.7efdd17.1710862426.19b449b3

I called the Credit Union. NO PROBLEMS at their end. I was asked which browser. I was told that Firefox is frequently the problem! I changed to Google Chrome and had NO trouble signing in.

I have had this problem previously with a few other websites.

ANY WAY for ME to fix the problem since I FAR prefer Firefox?

Thanks,Arthur

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

For the past week, when I sign into Facebook, the news feed is constantly refreshing itself. Once in a while the first post will stay, but the remainder of the news feed keeps refreshing. It is impossible to read anything as posts flash on and off, mostly off. The news feed is the only thing that is affected, visiting pages for likes and groups load and display properly, as do the games I play. The same occurs if in the private window mode. This does not happen if in the Chrome browser. What can be done to correct this situation?

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

while reading an MSNBC or Fox News article (for example) from flipboard, suppose there is a video at the top of the article. But I don't want to watch that video... I just want to read the article that appears below it. So I start to scroll down, reading the article, and when the video scrolls off the screen at the top, a picture-in-picture with that video appears at the right side of the article, (sometimes blocking part of the article). If I had wanted to see the video, I would have watched the video! STOP these blasted picture-in-picure pop-ups.

Every time I look for help online, all I see is how to enable/disable the PIP controls, and no help on how to block PIPs themselves.

Sorry for the long post, but I don't know how else to describe the problem succinctly. Jerry (at wit's end)

Whenever I log on to my bank's web site, I'm sent an audible signal that invites me to start a chat session with a bank agent. The problem is that the audible alert is so loud that it startles me. This is very annoying. I called the bank's help line and was told there was no way they could adjust the sound volume. I would like to know if it's possible for Firefox to decrease the volume for that web site.

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

AFTER RESETTING MY MACBOOK PRO I DISCOVERED THAT MY ALL MY PASSWORDS AND EMAIL SAVED TO MY ACCOUNT HAVE BEEN REMOVED/DELETED. PLEASE HELP WITH THIS PROBLEM AS SOON AS POSSIBLE. THANK YOU.

I've just switched to firefox from brave, and theres no button on twitch to enable picture in picture. Using the keyboard shortcut (cmd+option+shift+]) works, but I'd much rather click something on the screen. On brave there used to be a picture in picture button alongside settings, theatre mode, and fullscreen buttons, but on firefox this has been replaced by a clip button. There's no option for it if I right click (this works on youtube), and no option in the address bar for either twitch or youtube. I've tried disabling all my extensions and lowering protections but nothing seems to work.

I have Firefox on Windows, Linux, and Android. Anytime I use Firefox on a desktop, it sends me to Tornado Alley in Kansas. However, I am not in Kansas, and I don't have dog named Toto either. I am in the Detroit area. If I use other browsers, I don't have this problem. It only happens on desktop computers. On my cell phone it shows the correct location. I have already done the simple troubleshooting measure (for a year now: clearing cache, uninstall, reinstall, etc...) and NOTHING removes me from this Tornado Alley, Kansas location on the Firefox browser. If I use Chrome, Opera, Edge, etc... I don't get this problem. It must be something in the Firefox program.

Macos sonoma m1 - firefox is default browser, duck duck go is default search engine

When doing a search directly from searchlight options, firefox uses google search instead of the duck duck go default.

All other searches from within firefox uses the default correctly.

Long time technical, firefox user. One day starting firefox caused the system to slow unacceptably down. No changes before other than a possible background update from v122. Tried to do a Fresh Firefox v123, but firefox is attempting/constant localhost connections (ports in 40k-65k range) (attached screenshot).

It's on a Windows 10 desktop, uninstalled Firefox v123, manually deleted %appdata%\mozilla and %localappdata%\mozilla, reinstalled firefox, as soon as firefox.exe executes, I get constant localhost connection attempts from the "firefox.exe" process (Process Monitor image attached).

ran about:processes, found it was the "Network" category causing the problem. Permalink to report... https://share.firefox.dev/4972weA

Ran dism, it found no system files had issues. Only firefox has an issue, the system is great without it running.

Is this a bug?

What does firefox use the localhost connection for?

Is there a secondary component that is required by firefox that it is not running on execution that it is looking for?

Hello,

I have a problem with Firefox on Linux, doesn't seem to be distro specific as I've tried Manjaro/Ubuntu/Neon, when using KDE in that when listening to music on YouTube music my computer will go to sleep after the elected time. On KDE you can see which applications are preventing sleep and/or screen lock, other applications are listed here but not Firefox.

When playing a video everything works as expected.

I would investigate myself, but I don't know where to start so if someone can point me in the right direction or offer any insights?

Currently using: KDE Neon KDE 6.0 Kernel 6.5.0-21 Wayland
